Carotid endarterectomy is the gold standard for symptomatic carotid artery stenosis, as trials show no equivalent risk for stenting. Long-term data is pending, and stenting for asymptomatic stenosis lacks study support.

Area of Science:

  • Vascular Surgery
  • Interventional Cardiology
  • Neurology

Background:

  • Carotid artery stenosis poses a significant risk of stroke.
  • Carotid endarterectomy (CEA) and carotid artery stenting (CAS) are primary interventions.
  • Evidence comparing CEA and CAS is crucial for clinical decision-making.

Purpose of the Study:

  • To compare the periprocedural risks and long-term outcomes of CEA versus CAS.
  • To evaluate the current evidence supporting interventions for symptomatic and asymptomatic carotid artery stenosis.

Main Methods:

  • Analysis of data from multiple large randomized trials involving over 2,000 patients.
  • Focus on patients with predominantly symptomatic carotid artery stenosis.
  • Review of available long-term outcome data.

Main Results:

  • No trial definitively established equivalent periprocedural risk between CEA and CAS.
  • Long-term outcome data for both procedures is still pending.
  • Current study data does not support endovascular treatment for asymptomatic carotid stenosis.

Conclusions:

  • Carotid endarterectomy remains the established gold standard for symptomatic carotid artery stenosis.
  • Further long-term studies are required to fully compare CEA and CAS.
  • The frequent use of CAS for asymptomatic stenosis is not evidence-based.
